8 Sheets-Sheet 6 ZZ/I U Patented Ma 2, 1972 8 Sheets-Sheet 7 APPARATUS FOR ERECTING POURED CONCRETE STRUCTURES This invention relates to apparatus and a method for erecting poured concrete structures, and more particularly, to apparatus and method for erecting poured concrete structures such as dwellings using mechanized, reusable, easily transportable pouring forms.

The need for relatively inexpensive, easily constructed housing has generated a wide variety of proposals for so-called industralized housing. For example, it has been suggested that buildings be constructed from factory-cast concrete components. One such proposal is described in detail in US. Pat. No. 2,372,200. It has also been proposed that individual rooms, apartments or other modules" be manufactured offsite, and subsequently transported to the building site to be integrated into the finished structure.

The foregoing techniques both enjoy the distinct advantage of requiring relatively little skilled on-site labor, the need for such labor being associated with conventional on-site concrete pouring techniques.

conventionally, poured concrete work requires the accurate assembly of complex forms, the forms being dis-assembled, and often discarded, after completion of the job.

' On the other hand, in conventional on-site pouring, there is the advantage of not having to transport large finished structural elements to the job site. In some locations, such as congested urban areas and rural areas away from suitable roads, the transportation problem is of critical importance.

It is an object of the present invention to provide an apparatus and method whereby structures may be rapidly and efficiently erected by on-site pouring of concrete.

It is another object of this invention to provide an apparatus which provides a simple mechanized pouring form, capable of use for vertical as well as horizontal structural members.

It is yet another object of this invention to provide an apparatus and method whereby a number of adjoining poured concrete structures can be simultaneously erected.

It is still a further object of this invention to provide an apparatus providing mechanized concrete pouring forms, which is easily transported to and from a job site.

Other objects will appear hereinafter.

In a presently preferred fonn of the apparatus, the apparatus is supported on running gear, which render it roadable, and therefore easily transported to and from the job site. The running gear supports a superstructure, to which movable pouring form members are coupled. The pouring form members may be placed in a variety of positions, including positions wherein their surfaces are generally vertically oriented and face laterally outwardly with respect to a longitudinal centerline of the apparatus; and positions wherein they are disposed horizontally, facing upwardly. In the first-mentioned positions, the forms facilitate pouring of a vertically oriented member, such as a wall. In the second positions, pouring of horizontally oriented members, such as roofs and floors is possible.

In the preferred form of the apparatus, the movable pouring forms and the structure upon which they are mounted, are made selectively vertically movable with respect to the running gear. With such an arrangement, it is possible to complete pouring of a lower portion of the vertically oriented structural members, and then elevate the forms to accomplish pouring of upper portions of these members.

With the above-described apparatus, a dwelling or other structure can be erected in the following manner: the apparatus may be towed to the job site, and emplaced at a position between the intended positions for the side walls of the structure. The pouring forms associated with the apparatus can then be extended to positions wherein their outer faces correspond to the intended positions of the inner faces of the wall members. Other apparatus can be placed along side the first to provide forms defining the outer surfaces of the walls. Alternatively, however, conventional forms may be erected in juxtaposition with the apparatus-carried forms. Portions of the walls may then be poured by simply providing material to fill the voids between the forms. Such material may be provided in the conventional manner, or, in one presently preferred form of the invention, through pressure fittings associated with the apparatus-mounted forms.

If it is desired that the side walls extend upwardly for a distance greater than the height of the apparatus-mounted forms, the forms, and the superstructure upon which they are mounted, may be raised vertically with respect to the groundsupported chassis of the apparatus. Thus, the forms may be positioned above the first-poured portions of the walls, to facilitate pouring of upper wall portions.

If it is desired that the walls extend upwardly still further, the present apparatus provides for pouring of further portions in a unique manner. The apparatus-mounted forms in accordance with the present invention are provided with retractable projections, which form recesses in the inner surfaces of the side wall. The ground-supported chassis and the superstructure upon which the forms are mounted are provided with selectively operable recess-engaging members. Such members, with the actuator for raising the superstructure, permit the entire apparatus to climb the partly completed wall to facilitate pouring of the upper portions. Walls up to four stories high may be erected in this manner.

After completion of the vertical walls, the pouring forms are rotated to horizontal positions, wherein they facilitate pouring of a roof panel. The apparatus can then be lowered with the forms in their horizontal positions, so that successively lower horizontally extending interior members can be poured.

After completion of the poured structure, pre-cast or other pre-assembled facings may be applied to the ends of the poured structure to complete the building enclosure.

By providing several of the above-described apparatus in side-by-side relation, and operating them simultaneously, a large number of adjoining row" type structures can be erected in a relatively short period of time, and with a minimum of labor.

For the purpose of illustrating the invention, there is shown in the drawings a fonn which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

Referring now to the drawings in detail, wherein like numerals indicate like elements, there is seen in FIG. 1 a rowtype multiple dwelling, designated generally by the reference numeral 10. The dwelling comprises individual attached units, such as the units designated 12, 14 and 16.

FIG. 2 illustrates in a general manner the major structural components of the dwelling 10. Thus, referring to FIG. 2, a monolithic poured concrete load-bearing structure, designated generally by the reference numeral 18, is provided. The structure 18 rests on a slab 20, and includes spaced vertically extending walls 22 and 24; a roof panel 26; and a floor panel 28. Prefabricated wall panels, such as the wall panels 30, 32, 34 and 36 finish the front face of the dwelling 10, and provide suitable openings for windows, such as the window 38, and a doorway 40. The wall panels may be affixed to the loadbearing structure 18 in any suitable manner, such as by means of clips, not shown.

Wall panels 42, 44, 46 and the like are affixed to the rear of the load-bearing structure 18 in the same manner as the wall panels 30 to 36.

Referring now to FIGS. 3 and 4, there is seen an apparatus, designated generally by the reference numeral 48, in accordance with the present invention.

The apparatus 48 includes a lower chassis portion, designated generally by the reference numeral 50, provided with running gear, such as the illustrated wheels 52 and axles 54, 56. The lower chassis portion 50 supports a superstructure, or upper chassis portion 58. For this purpose, an adjustable linkage, designated generally by the reference numeral 60, is provided. It should be understood that the adjustable linkage 60 seen in FIG. 3 is merely illustrative of a wide variety of linkages which could be used. In the illustrated form, a pair of links 62 disposed on opposite sides of the lower chassis portion 50 have corresponding ends pivotably coupled to side rails 64 of the lower chassis portion 50. Another pair of links 66 have medial portions pivotably coupled to the links 62, and have respective ends thereof slidably coupled to the side rails 64. For this purpose, there is seen in FIG. 3 a slot 68 in one of the side rails 64. Operation of an actuator 70 causes relative rotation of the respective pairs of links 62 and 66 with respect to each other and the lower chassis portion 50. Such rotation results in elevation of the superstructure 58. The reason for such elevation will be explained later.

Also affixed to the lower chassis portion 50 are selectively extensible abutment members 72. With reference to FIG. 4, similar abutment members 74 are associated with the superstructure 58. The purpose of the abutment members 72 and 74 will also be explained later.

Referring to FIGS. 3, 4 and 5, pouring form members 76 and 78 are movably coupled to the upper chassis portion 58 for movement between the positions illustrated in FIGS. 3, 4 and 5, wherein their outer surfaces are oriented generally vertically, facing laterally outwardly with respect to the chassis portions; and the positions shown in FIGS. 9 and 10', wherein their outer surfaces are oriented generally horizontally, facing upwardly. In their vertical orientation, the pouring form members 76 and 78 may assume raised positions, suitable for travel (FIGS. 4, 5 and 6) or lowered and extended positions (FIGS. 7, 8, 13, etc.) to facilitate pouring of vertically oriented structural members. An'y' suitable mechanical interconnection may be provided between the upper chassis portion 58 and the pouring form members 76 and 78 to provide for the abovementioned movement. In the illustrated form of the invention, with reference to FIGS. 3, 4 and 5, spaced upwardly extending support brackets 80 and 82 are provided on the upper chassis portion 58. The pouring form members 76 and 78 are provided with inwardly extending brackets 84 and 86, at spaced locations corresponding to the locations of the support members 80 and 82 on the upper chassis portion 58. The support members 80 and 82, as is perhaps best seen in FIG. 5, are provided with guide slots 88 and 90, defining the paths of movement of the pouring form members 76 and 78. Guide bars 92 and 94, the ends of which are affixed to the brackets 84 and 86 associated with each of the pouring form members 76 and 78, extend through the guide slots 88 and 90.

Referring to FIGS. 4 and 5, pairs of remotely actuable fluid operated cylinders 96, 98, and 102, associated with the guide bars 92 and 94, serve to move the pouring form members 76 and 78 by causing the guide bars 92 and 94 to traverse the guide slots 88 and 90.

Referring now to FIGS. 6 and 7, the manner in which the apparatus 48 may be used to erect a building, such as the dwelling 10, will now be described.

Assuming that a suitable slab 20 has been provided, the apparatus 48 may be towed or otherwise moved into a position between the intended positions of the vertically oriented walls 22 and 24. If the structure to be erected is of the row type, other apparatus, designated by the reference numeral 48' and 48" may be positioned alongside the apparatus 48. The pouring form members 76 and 78 of the apparatus 48 may then be lowered from their raised positions shown in FIG. 6, and projected laterally outwardly in the direction of the arrows, to assume their operative positions, illustrated in FIG. 7. The pouring form members 78 and 76" of the apparatus 48 and 48" are similarly positioned. Thus, as is most apparent from FIG. 7, concrete can now be poured between the pouring form members 76 and 78' and 78 and 76". Setting of such concrete provides lower portion 22 of the wall 22.

The lower portion 22' of the wall 22 is provided adjacent its upper end with a series of spaced apertures 104. Such apertures 104 are formed by respective projections 106 and I08, associated with the forms 76 and 78', respectively. Referring to FIG. 6, the pouring form 78 of the apparatus 48 is itself provided with a row of projections 108, which are juxtaposed during pouring to projections 106" associated with the form 76".

Referring once again to FIG. 3, it is seen that the projections 106 associated with the form 76 are affixed to a panel forming an edgewise extension of the form member 76. A similar panel 112, which carries the projections 108, not seen in FIG. 3, is associated with the form member 78. The panels 110 and 112 are hingedly connected to the respective form members 76 and 78. The purpose of this arrangement will be explained in greater detail later.

Referring now to FIG. 8, the manner in which upper portions of the walls 22 and 24 are poured will now be described. Assuming that the lower portion 22 of the wall 22 and a lower portion 24 of the wall 24 have been poured, the pouring form members 76 and 78 can be drawn by means of the cylinders 96, 98, 100, 102 away from the finished portions, and the upper chassis portion 58 of the apparatus 48 elevated with respect to the lower chassis portion 50. Such elevation is accomplished by operation of the actuator 70 (not seen in F IG. 8), to cause relative rotation of the pairs of links 62 and 66. The form members 76 and 78 can then be projected to the positions seen in FIG. 8, wherein they are positioned for pouring of further portions 22" and 24" of the respective walls 22 and 24. Pouring form members 78 and 76" associated with adjacent apparatus 48' and 48" are placed in juxtaposition to the forms 76 and 78. As an alternative, conventional forms may be erected in juxtaposition to the apparatus-mounted form members 76 and 78. Pouring of the portions 22" and 24" may then proceed as before.

In FIG. 9, the manner in which a horizontal structural element, such as the roof panel 26, may be poured, is illustrated.

Suitable actuation of the fluid cylinders 96, 98, 100 and 102 effects retraction of the pouring form members 76 and 78 from their positions shown in FIG. 8, and also effects their rotation to the position illustrated in FIG. 9. The function of the above-mentioned panels 110 and 112 should now be apparent. As the form members 76 and 78 approach their horizontally oriented positions, latching means, not shown, are released to permit the panels 110 and 112 to fold with their projections 106 and 108, out of the planes of their respective pouring form members 76 and 78. The panels 110 and 112, therefore, facilitate removal of the projections 106 and 108 from the plane defined by the form members 76 and 78.

The pouring form members 76 and 78 abut at the edges adjacent the hinge lines of the panels 110 and 112 to form a continuous face against which the roof panel 26 may be poured. Material forming the roof panel 26 flows into the apertures 104 in the upper wall portions 22" and 24". Setting of such material results in a strong mechanical interconnection between the roof panel 26 and the walls 22 and 24.

FIG. illustrates the positions of the pouring form members 76 and 78, and the upper chassis portion 58 during pouring of an internal horizontal member such as the floor panel 28. The pouring form members 76 and 78 are in their horizontally disposed upwardly facing positions. The height of the upper chassis portion 58, adjusted by means of the actuator 70 (not seen in FIG. 10) is such that the plane defined by the pouring form members 76 and 78 is on a level with the apertures 104 in the wall portions 22 and 24'. The material forming the floor panel 28 flows into the apertures 104 to form a strong mechanical bond between the floor panel 28 and the walls 22 and 24. Floor panels 28 and 28" in adjacent sections of the structure 18 can be poured simultaneously with pouring of the floor panel 28. The result of such simultaneous pouring is that the floor panels 28, 28 and 28" are in fact parts of a monolith, interconnected by portions extending through the apertures 104. After setting of the floor panels 28, 28', the upper chassis portion 58 can be lowered, and the apparatus towed from the slab.

FIGS. 11 to 13 illustrate an important aspect of the present invention, namely the manner in which the apparatus 48 can be made to elevate itself with respect to finished lower wall portions. In this manner, additional upper wall portions can be poured, the number being limited only by the stability of the partly completed walls.

Referring now to FIG. 11, the upper chassis portion 58 is seen in an elevated position, after withdrawal of the form members 76 and 78 from the wall portions 22" and 24". The upper chassis portion 58 has been elevated to a point at which the previously mentioned abutment members 74 associated therewith are in horizontal alignment with the apertures 104 in the walls 22 and 24. Thus, as is seen in FIG. 11, the abutment members 74 can be projected into the apertures 104. If the actuator 70 is next operated to lift the lower chassis portion 50, the abutment members 74 and wall portions 22 and 24 assume the weight of the apparatus 48.

In FIG. 12, the apparatus 48 is seen with the lower chassis portion 50 fully raised. In such position, referring to FIG. 14, the abutment members 74 on the upper chassis portion 58 (hidden in this Figure) and the abutment members 72 on the lower chassis portion 50 are in horizontal alignment, and both in alignment with one of the apertures 104.

Referring to FIG. 13, it should now be apparent that if the abutment members 74 associated with the upper chassis portion 58 are withdrawn, the abutment members 72 associated with the lower chassis portion assume the entire weight of the apparatus 48. Retraction of the abutment members 74, however, frees the upper chassis portion 58 for further upward extension with respect to the lower chassis portion 50. In FIG. 13, the upper chassis portion 58 is shown in a raised position, wherein the form members 76 and 78 are positioned for pouring of wall portions 22" and 24", disposed above the previously completed portions of the walls 22 and 24. If it is desired to pour still higher than the wall portions 22" and 24", the lower chassis portion 50 of the apparatus 48 may be placed in the dotted-line position in FIG. 12 by the following sequence of operations.

The upper chassis portion 58 is positioned so that the nowretracted abutment members 74 are in alignment with apertures 104 in the walls 22 and 24. The abutment members 72 are then retracted with respect to the lower chassis portion 50, and the lower chassis portion 50 drawn up to the dotted-line position. The abutment members 72 are then again projected, and the abutment members 74 retracted. With the apparatus 48 thus configured, the actuator 70 may be used to again raise the upper chassis portion 58 to facilitate pouring of upper wall portions.

In one presently preferred form of the apparatus, wherein the pouring form members 76 and 78 are each 8 feet in height, it is feasible to pour vertically oriented walls as high as four portions, or 32 feet, in height. Each portion, of course, represents a single story of the finished building. The depth of the building, front to rear, is determined by the length of the pouring form members 76 and 78. In the presently preferred form, the pouring form members are 32 feet in length.

Referring to FIGS. 3, 4 and 15, the manner in which apparatus such as the above-described apparatus 48 may be interconnected to simultaneously erect adjacent building units is illustrated.

Referring first to FIGS. 3 and 4, gage bars 114 and 116 are coupled to the apparatus 48 at front and rear. The gage bars 114 and 116 are pivotably mounted on axes 118 extending in a direction parallel to the longitudinal axis of the apparatus 48. The gage bars 114 and 116 rotate in planes perpendicular to the axes 118. Referring now'to FIG. 15, it is seen that interconnection of the gage bars 114 and 116 on adjacent apparatus 48, by means of any convenient coupling, establishes parallelism of the adjacent apparatus 48, and also establishes a standard spacing therebetween. Thus, assuming evenness of the slab 20 upon which the apparatus 48 rests, interconnection of the gage bars in the manner shown in FIG. 15 ensures proper positioning of the various pouring form members.

Referring again to FIGS. 3 and 4, means are shown associated with the apparatus 48 to facilitate delivery of concrete to the forms, once positioned. For this purpose, there is seen a reservoir 120 for a quantity of material. Extending therefrom are suitable flexible conduits 122, 124 and 126, associated with the pouring form members 76 and 78. Material passing through the conduits 122, 124 and 126 emerges through openings, such as the openings 128, 130 and 132, seen in FIG. 3 on the pouring form member 76. The abovedescribed structure, it will be appreciated, facilitates delivery of concrete to the outer faces of the pouring form members 76 and 78, and can be used, if desired, to eliminate the need for conventional material delivery systems used in the pouring of concrete. Pumps, or the like, not shown, deliver material from the reservoir 120, and propel such material through the conduits 122, 124 and 126, and through the openings 128, 130 and 132.

In one of its aspects, the present invention resides in a method of erecting a concrete structure, in the following manner.

A site is leveled and a slab, such as the slab at 20, emplaced thereon. During placement of the slab, upstanding rods, such as the rods 134 and 136 illustrated in FIG. 7, may be placed in rows defining the intended positions of walls. The apparatus 48 may then be in positioned on the slab, and the pouring forms 76 and 78 positioned to facilitate pouring of the wall portions 22 and 24'. After pouring and setting of the wall portions 22' and 24', the pouring forms are retracted and then raised, by operation of the actuator 70, to positions facilitating pouring of the wall portions 22" and 24".

If the desired structure 18 is to be only two stories in height, the pouring forms 76 and 78 can be rotated and positioned to facilitate pouring of the roof panel 26. After pouring and setting of the roof panel, the actuator 70 may be operated to lower the pouring forms 76 and 78 to positions wherein the floor panel 28 is poured. After pouring and setting of the floor panel 28, the pouring forms 76 and 78 may be further lowered away from the floor panel 28, and the apparatus 48 withdrawn from between the walls 22 and 24.

As has already been explained, in practicing the present method, apertures 104 are fonned in the wall portions 22, 24, 22", and 24". If it is desired to erect a structure 18 having more than two stories, the method includes steps of projecting the abutment members 74 into engagement with the apertures 104, operating the actuator 70 to bring the abutment members 72 associated with the lower chassis portion 50 up to the level of the abutment members 74, retracting the abutment members 72, and operating the actuator 70 to lift the pouring forms 76 and 78 to levels necessary for pouring of further wall portions. When the wall portions are erected to their desired height, roof panels and interior horizontals are formed in the abovedescribed manner by successively lowering the pouring form members 76 and 78 and the apparatus 48, until the apparatus 48 again rests on the slab and pouring and setting of the lowest interior horizontal is completed.

The present apparatus 48 is preferably of roadable dimensions (no more than 10 feet in width) when the pouring forms 76 and 78 are in their retracted positions. The present method and apparatus permit rapid erection of a structure 18 and completed dwelling 10. Individual wall portions of 8 foot height can be completed overnight. Moreover, by using several apparatus 48 in side-by-side relation, rather than conventional forms, large numbers of row-type units can be erected in a short period of time.

Although not illustrated herein, those skilled in the art will appreciate that suitable reinforcing elements, such as steel mesh, rods or the like, can be incorporated into the poured structural members described herein, by simply positioning such members with respect to the pouring forms prior to pouring of the material.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope ofthe invention.
